# Antares -> Octopus 8

Rust utility to fetch product data from Antares B2B and export to Excel which can be imported by Octopus 8.

## Quick Start

Linux / MacOS:

```bash
cp .env.example .env
# Edit .env with your credentials and output path
cargo build --release
./target/release/antares_get_data
```

Windows:
```batch
copy .env.example .env
REM Edit .env with your credentials and output path
cargo build --release
./target/release/antares_get_data.exe
```

## Configuration

`.env` file:
```env
URL=https://b2b.antares.hu/YOUR_BASE_URI_HERE
ANTARES_USERCODE=given_usercode
ANTARES_PASSWORD=given_password
OUT=out\\test.xlsx
```

`OUT` can be:
- Directory: `out` → creates `out/antares.xlsx`
- File path: `exports/data.xlsx` → creates file there
- Must be `.xlsx` extension if file path

## How It Works

1. Load credentials from `.env`
2. Fetch product data from Antares B2B API (600s timeout)
3. Save raw JSON to `antares.json`
4. Export filtered data to Excel
5. Log all operations to `log/YYYY-MM-DD.log`

## Excel Output

8 columns with selective field mapping and row filtering:

| Column | Source |
|--------|--------|
| BESZCIKKSZAM | [cikkszam](./src/template/antares.rs#L21) (required) |
| GYCIKKSZAM | [cikkszam](./src/template/antares.rs#L21) |
| BESZCIKKNEV | [cikk_megnevezes_rovid](./src/template/antares.rs#L21) or [cikk_megnevezes](./src/template/antares.rs#L20) (required) |
| GYARTO | "EGYEB" (const) |
| CIKKAZON | [vonalkod](./src/template/antares.rs#L33) |
| KESZLET | [szabad_keszlet](./src/template/antares.rs#L29) |
| ME | [mennyisegi_egyseg_kod](./src/template/antares.rs#L24) |
| EGYSEGAR | [netto_kisker_ar](./src/template/antares.rs#L26) or "Alap ár" [jellemzo](./src/template/antares.rs#39).[jellemzo_nev](./src/template/antares.rs#L41) |

Rows skipped if `BESZCIKKSZAM` or `BESZCIKKNEV` missing!

## Project Structure

- `src/main.rs`: Main application logic
- `src/api/`: API client functionality
- `src/template/`: Data structures for Antares JSON response
- `src/tools/`: Utility modules (logger, env loader, request handler, Excel exporter)
- `Cargo.toml`: Rust dependencies and project configuration

## Building

The project uses Cargo (Rust's package manager). To build:

```bash
cargo build --release
```

This will create an optimized binary in `target/release/antares_get_data` (or `antares_get_data.exe` on Windows).

## Running

1. Copy `.env.example` to `.env`
2. Edit `.env` with your credentials and output path
3. Run the application:

```bash
./target/release/antares_get_data
```

Or on Windows:
```batch
./target/release/antares_get_data.exe
```

## Debug Mode

To preserve temporary files for debugging, run with the `--debug` flag:

```bash
./target/release/antares_get_data --debug
```

This will prevent cleanup of the `temp/` directory which contains the raw JSON response from the API.
